I have a points shapefile (villages) that are located in remote areas in Africa. I need to give each village a measure of "remoteness." I dont just want to do a "as the crow flies" calculation from the village point to the nearest paved road. Can anyone give me specific instructions on how to do so? I'm using ArcGIS.
I know there are things like Grass R walk module and Naismith's Rule/Dijkstra's Shortest path Algorithm and using some combination of slope and topo rasters, but very specific instructions are much needed. I have a point shapefile with all the village points and a roads shapefile (but the villages are obviously very far away from the road network for the most part - at least the road network shapefile that is available to me)
